I have issue on connecting LS server one multiple page

rvkvino

(App developed myusing Ionic Cordova platform .)
I have an application like trading platform. In my first page, I need to display all of the live rates(List of stocks and their rates). If they click on trade button I need to display only what every tradable stock. And If click on the stock from this I need to display responding stock details and Bid and Ask price and from this screen, users will submit their required quantity and submit the page. For every page currently, i'm opening the new connection.

var protocolToUse = document.location.protocol != "file:" ? document.location.protocol : "http:";
var portToUse = document.location.protocol == "https:" ? "443" : "8080";
var lsClient = new Lightstreamer.LightstreamerClient(protocolToUse+"//domain.com:"+portToUse,"STOCKLIST_REMOTE");
lsClient.connect();

As like that connecting in all of my three pages. But If I navigate the pages means connection getting close automatically. Showing the error like session terminated. Could you please help me anyone to fix this issue. Or else id there any other way to share the connection(connectionSharing) from one page to another page. I have tried like below code but issue happens. It says have to add connection sharing library.
lsClient.connectionSharing.enableSharing("CommonConnection", "ATTACH", "CREATE");
And also I need if we use connectionsharring means how to use that shared connection in another page.
I have below code in all of my three page controller(I'm using ionic framework for my android application )
var protocolToUse = document.location.protocol != "file:" ? document.location.protocol : "http:";
var portToUse = document.location.protocol == "https:" ? "443" : "8080";
var lsClient = new Lightstreamer.LightstreamerClient(protocolToUse+"//domain.com:"+portToUse,"STOCKLIST_REMOTE");
lsClient.connectionOptions.setHttpExtraHeaders({"username" : "bullion"});
lsClient.addListener({
onStatusChange: function(newStatus) {
console.log(newStatus);
}
});
lsClient.connect();

Hi rvkvino,

ConnectionSharing is the object of our client API that allow to specify if and how the connection is shared between different LightstreamerClient instances.
If you are using a versiont 7.0.x of Lightstreamer Web Client this is the correct syntax to leverage the engine sharing:

lsClient.enableSharing(new ConnectionSharing("my_sharing_name", "ATTACH", "CREATE"));

If you've built your library with the provided generator,please make sure you've included the ConnectionSharing class.

I confirm that the code should be the same in all your pages and the Lightstramer client will manage out of the box the sharing of a single connection to the server across all LightstreamerClient instances.

Please, take also a look at this demo that shows a quite similar scenario.

Regards,
Giuseppe

Hi,
I have used the code as like below in my all the 3 pages.
var protocolToUse = document.location.protocol != "file:" ? document.location.protocol : "http:";
var portToUse = document.location.protocol == "https:" ? "443" : "8080";
var lsClient = new Lightstreamer.LightstreamerClient(protocolToUse+"//domain.com:"+portToUse,"STOCKLIST_REMOTE");
lsClient.connectionOptions.setHttpExtraHeaders({"username" : "bullion"});
lsClient.enableSharing(new Lightstreamer.ConnectionSharing("CommonConnection", "ATTACH", "CREATE"));
lsClient.addListener({
onStatusChange: function(newStatus) {
console.log(newStatus);
}
});
lsClient.connect();
This idn't work for me, If I navigate from first page to second page stock table didn't display. Connection status showing like connected. AS like this demo I dind't create single lsClient.js file and define into my controller.

rvkvino

I have changed the functionality as like below,
First created global file and in it created lsclient variable and created a connection on that. And for slave pages I have connected and subscribe the LS Server.
Global Declaration :Smile_Ac: lsconnection.js)
var protocolToUse = document.location.protocol != "file:" ? document.location.protocol : "http:";
var portToUse = document.location.protocol == "https:" ? "443" : "8080";
var lsClient = new Lightstreamer.LightstreamerClient(protocolToUse+"//mydomain.com:"+portToUse,"SLNSTOCKLISTDEMO_REMOTE");
lsClient.connectionOptions.setHttpExtraHeaders({"username" : "bullion"});
lsClient.enableSharing(new Lightstreamer.ConnectionSharing("CommonConnection", "ATTACH", "CREATE"));

And my all the 3 pages used as like below(slave page)
lsClient.connect();
var liverateSubscription = new Lightstreamer.Subscription("COMMAND", liverateId, fieldList);
//my subscription
var liverateId = "Item";
var fieldList = ["key", "command", "desc", "bid", "ask", "high" , "low", "order"];
var bidaskfieldsList = ["desc", "bid", "ask", "low" , "high", "ratedisplay", "updatetime", "msg"];
var bidaskitemList = ["Gold", "Silver", "INR", "MGold", "MSilver", "Marketstatus"];

var liverateSubscription = new Lightstreamer.Subscription("COMMAND", liverateId, fieldList);
var liverateGrid = new Lightstreamer.DynaGrid("liverates",true);
liverateGrid.setAutoCleanBehavior(true,false);
liverateGrid.addListener({
onVisualUpdate: function(key,info) {
if (info == null) {
return;
}
info.forEachChangedField(function(fieldName,val) {
var lastPrice = info.getChangedFieldValue(fieldName);
if (lastPrice !== null) {
var prevPrice = liverateGrid.getValue(key,fieldName);
if(prevPrice != null){
if (!prevPrice || lastPrice > prevPrice) {
info.setAttribute("#2636f2",null,"backgroundColor");
info.setAttribute("#FFFFFF",null,"color");
} else {
info.setAttribute("#FF0000",null,"backgroundColor");
info.setAttribute("#FFFFFF",null,"color");
}
}
} else {
info.setAttribute("",null,"backgroundColor");
info.setAttribute("",null,"color");
}
});

}
});
liverateGrid.setSort("order", false);
liverateSubscription.setDataAdapter("QUOTE_ADAPTER");
liverateSubscription.setRequestedSnapshot("yes");
liverateSubscription.addListener(liverateGrid);
lsClient.subscribe(liverateSubscription);
It is working without terminate the session. But showing unchanged text everywhere mostly. Whenever the rates getting change at that time only showing the rates, after that showing only UNCHANGED text. Attached the screenshot for your reference.

Hi rvkvino,

Please could you confirm that every slave pages declare its own instance of lsClient?

Thank you,
Giuseppe

rvkvino

Could you please give me the code sample that creating an instance from lsClient. I have tried but showing lsClinet not having constructor method.

Giuseppe Corti

Hi rvkvino,

Basically, in every page you should have something like this

var lsClientPageX = new LightstreamerClient(protocolToUse+"//mydomain.com:"+portToUse,"SLNSTOCKLISTDEMO_REMOTE");

lsClientPageX.enableSharing(new Lightstreamer.ConnectionSharing("CommonConnection" , "ATTACH", "CREATE"));

Regards,
Giuseppe

rvkvino

Hi,
I have tried this already, But what happens means if I give this connection to open all the page means It terminating the session and continuously trying to reconnect the session. While I navigate the tabs more than 3 times means it disconnect the session.

Giuseppe Corti

Hi rvkvino,

Any chance to collect the client log of one of the page?
You should add to your code something like this:

[SYNTAX=JS]var loggerProvider = new SimpleLoggerProvider();
LightstreamerClient.setLoggerProvider(loggerProvider);

var cats = ["lightstreamer.sharing","lightstreamer.stream","lightstreamer.protocol","lightstreamer.session","lightstreamer.actions","lightstreamer.grids","lightstreamer.subscriptions"];
for (var i=0; i<cats.length; i++) {
var myAppender = new ConsoleAppender("DEBUG",cats);
loggerProvider.addLoggerAppender(myAppender);
}[/SYNTAX]

the log will appear in the browser console.

Regards,
Giuseppe

Hi,
I have tried this like below, It is working on my browser but not working on the device.
This file written in lsconnection.js and globally included in my application.
var protocolToUse = document.location.protocol != "file:" ? document.location.protocol : "http:";
var portToUse = document.location.protocol == "https:" ? "443" : "8080";
var lsClient = new Lightstreamer.LightstreamerClient(protocolToUse+"//mydomain.com:"+portToUse,"STOCKLIST_REMOTE");
lsClient.connectionOptions.setHttpExtraHeaders({"username" : "bullion"});
lsClient.enableSharing(new Lightstreamer.ConnectionSharing("CommonConnection", "ATTACH", "CREATE"));
lsClient.connect();

And all of my three controllers written the code like bellow and subscribed in this controller only.
var protocolToUse = document.location.protocol != "file:" ? document.location.protocol : "http:";
var portToUse = document.location.protocol == "https:" ? "443" : "8080";
var lsClient = new Lightstreamer.LightstreamerClient(protocolToUse+"//mydomain.com:"+portToUse,"STOCKLIST_REMOTE");
lsClient.connectionOptions.setHttpExtraHeaders({"username" : "bullion"});
lsClient.enableSharing(new Lightstreamer.ConnectionSharing("CommonConnection", "ATTACH", "CREATE"));
var liverateSubscription = new Lightstreamer.Subscription("COMMAND", liverateId, fieldList);

This working well without terminate the session on browser (ionic serve --lab). But not working after build the app and check in real device.

Giuseppe Corti

Hi rvkvino,

Please let me suggest some tests to be run:

1. Have you tried a very simple application with only one page and one subscription just to chek if is ok on a real device?
2. Could yuo tried your code without the lsClient.enableSharing(...) statement?

Regards,
Giuseppe

rvkvino

I have many application with one subscription on one page. I didn't get any issue on that application on real device.
And also I have tried in this application without using lsClient.enableSharing in this case losing the session after navigate 3 times between connected LS Server page.

We are on fire, Client making urgent to fix this issue soon. could you please help me to fix this issue soon.

Hi rvkvino,

If a single page application work fine, an application that handles 3 distinct and completely independent pages should work fine as well without leveraging the sharing; for sure you give up some optimization but the app still have to work.
The attached log refers to a scenario with the sharing active and also does not point out any kind of problem.

I would suggest to try to understand why the session was lost browsing through the pages.
Please could you collect the log in this specific case? Furthermore could you add application log in this LightstreamerClient event?

Regards,
Giuseppe

rvkvino

Please check now, I have commanded the connection sharing code and below code given in all the three page,
var protocolToUse = document.location.protocol != "file:" ? document.location.protocol : "http:";
var portToUse = document.location.protocol == "https:" ? "443" : "8080";
var lsClient = new Lightstreamer.LightstreamerClient(protocolToUse+"//mydomain.com:"+portToUse,"STOCKLIST_REMOTE");
lsClient.connectionOptions.setHttpExtraHeaders({"username" : "bullion"});
//lsClient.enableSharing(new Lightstreamer.ConnectionSharing("CommonConnection", "ATTACH", "CREATE"));
//lsClient.connectionOptions.setCookieHandlingRequired(true);

lsClient.addListener({
onStatusChange: function(newStatus) {
console.log(newStatus);
if(newStatus == "CONNECTED:HTTP-STREAMING"){
}else if(newStatus == 'DISCONNECTED:WILL-RETRY'){
}
}
});
lsClient.connect();

Now log shows like,

Hi rvkvino,

Also this log does not show anything wrong.
There are two sessions that start regularly and subscriptions are also successful.

Please, could you describe in detail the actions taken in the test and the wrong behavior observed?

Thank you,
Giuseppe

rvkvino

Please check this screen, I have explained in this images. I'm remain we are using ionic cordova framework to develop the app.

Hi rvkvino,

The snippet of log is not large enough to understand what's going on.
In any case it seems that the LightstreamerClient still try to share the connection.
Maybe that some of the LightstreamerClient instances you have in the client still require the enableSharing?

Could you try to force an explicit disconnect every time the user change page?

Regards,
Giuseppe

Hi,
As your instruction I have changed the code for every page(All 3 Pages). Now all the page will connect and disconnect when navigate to other page. And also removed sharing. Now also same issue if I connect the page 4 times means it is working after i navigate to same page 5th time it will disconnect the session and trying to reconnect (Status got RECONNECT). But not successfully connected. I need to close the app and restart the app then only connecting.

Hi rvkvino,

It's a strange behavior; an hypothesis that I have got is that ionic has a limited conection pool that once exhausted does not allow new connections (to the same host : port). Please could you check if this hypoetesis makes sense.
Furthermore, might also be helpful the Lightstreamer server log, with <logger name="LightstreamerLogger.connections" level="INFO"/> of a specific and limited test case.

Regards,
Giuseppe
